DPI Settings

In terms of resolution, existing applications will work without modifications. New devices will work
in one of two DPI implementations (not switchable) -- 96 DPI or 192 DPI. Devices that work in 96 DPI implementation (on a VGA screen) will simply use four "dots" to represent one dot (since the
increase in resolution over the previous one is a nice multiple of two, both horizontally and
vertically, see Figure 3 below). Devices that work in 192 DPI will display four times the amount
displayable in the 96 DPI implementation.

Figure 3. A 96 DPI implementation on a normal screen versus a 96 DPI implementation on a VGA screen.

Because of the increase in resolution (while the physical dimension remains the same), it is likely
that some users will have problems in reading the smaller text. Hence Microsoft has added a new
panel in the screen settings to allow the user to change the size of the text (see Figure 4).

Screen Orientation

Screen orientation is another important new feature in SE. As shown in Figure 5, you have the choice between a right-handed or left-handed orientation in landscape mode.

Figure 5. Choosing the display orientation.

For right-handed users, the screen is positioned so that the navigational buttons are to the left, and for left-handed users the navigational buttons are to the right (See Figure 6).

You can also change the orientation of the screen on-the-fly using the orientation button, depending on actual device implementation (see Figure 7).
